CD1.1 Tools for Platinum
It is possible to use CD1.1 under Platinum without using GDI
but, if any data received in different formats are to be
converted to CD1.1, they will first be converted to GDI and
passed via the gdi-base module.
For pure CD1.1 implementations, it is neither efficient nor
necessary to convert to and from GDI, so a separate CD1.1
multiplexor module is provided. Incoming CD1.1 frames are
not passed to GDI, so it is not possible to convert them into
non-CD1.1 formats, such as SEEDlink.
1.2 CD1.1 architecture
The CD1.1 tool suite consists of four modules:
•
The CD1.1 receiver (data-in-cd11), which receives
data in CD1.1. format from external CD1.1 data
producers (DPs);
•
The GDI to CD1.1 converter (gdi2cd11), which receives
data from GDI and, thus, indirectly, from any other
source in any supported format;
•
The CD1.1 multiplexer (data-mux-cd11), which accepts
and combines data from one or more instances of the
previous two modules; and
•
The CD1.1 sender (data-out-cd11), which takes data
from a CD1.1 multiplexer instance and transmits them
in CD1.1 format to external CD1.1 data consumers
(DCs).
Any useful configuration will, therefore, use at least three of
these modules. It is possible to configure more than one
instance of any of these modules and these can be connected
together as necessary when building more complex
implementations.
